RESEARCH REPORT			Danny Friedheim    pd. 2


   1. Which research area(s) is a match for the project(s) you are interested in?

	My research areas include steganography and steganalysis.

   2. Within the above research area(s), locate a project(s) that is similar to your interest.
          * Title of the project(s):

		Steganalysis of JPEG Images: Breaking the F5 Algorithm
             

          * Abstract of this project (describe in several sentences the focus and goal of the project(s)).

		The authors present a steganographic method for detecting and estimating the size of messages hidden in JPEG images using the F5 algorithm.  Their method is able to reliably detect messages that have modified as little as 10% of the data in the image.  The purpose of this method is to detect the presence of messages in JPEG images (which is the general goal of all of steganalysis), in order to then use other algorithms to try to extract the data.


          * What is the analysis being done, how is the project analyzed for success?

		The project is analyzed for success by determining how accurately the algorithm can detect modified JPEGs and how little modified data it was able to discover.  As I said earlier, the method was proven to detect modifications of as little as 10% of the image data.            	
               

          * What are the results and conclusions? What are areas for continued research? (if this can be determined)

		The method is considered a success at detecting the presence of F5-encoded messages in JPEG images, which had never been done with much success before.  The authors concluded that the algorithm will give a false positive approximately 1 in 10^8 and will miss a message at a rate of no worse than 1 in 10^7.  Areas of continued research could include use of a similar algorithm on other image formats, though JPEG has been known to be the most difficult so far.

   3. What software (computer languages) was used in this project you've found (if this information is available.

	The paper did not make it clear which languages were used for the image manipulation and statistical analysis, but C is probably likely.
       

   4. What software (computer language(s)) do you expect to use in your own project.

	I expect to use mostly C++, but possibly also some Java or Python.
